| Abstract: | The results of studying the spectral properties of strontium titanate single crystals (grown under different conditions), both pure and activated by iron-group or lanthanide ions, are presented. The data on the main color centers and the formation of systems of ordered crystallites from 10−7 to 10−9 m in size on the sample surface after treatment in plasma are obtained by optical and X-ray spectroscopy, cathodoluminescence, electron microscopy, and atomic-force microscopy. |
